Cinc Auditor vs kubeconform

Cinc Auditor is a free distribution of Chef InSpec for compliance and audit workflows on Linux, macOS, and Windows. Its profiles are fully compatible with upstream counterparts, and its tools work with InSpec; an InSpec wrapper redirects to Cinc Auditor so existing automation can keep working. Installation options include scripts, Bundler, RubyGems, and plain packages. Cinc also publishes a Docker Hub image as a drop-in replacement for chef/inspec. It can run InSpec-compatible profiles in CI or against containers, with GitLab CI and GitHub Actions named as examples. Auditor is included in Cinc Workstation. Cinc says its binaries use the Apache 2.0 license without additional EULAs or licensing. The project does not provide formal warranties or support, and it does not currently offer repositories for standard package managers such as yum or apt. The free plan costs nothing. Cinc recommends contacting Progress for warranty or support needs.

Kubeconform is a command-line tool for validating Kubernetes manifests before deployment. It checks files against Kubernetes OpenAPI specifications, helping catch configuration problems before they reach a cluster. Validation and schema downloads run concurrently, and downloaded files are cached in memory. By default, it uses a self-updating fork of the Kubernetes JSON schema registry to supply schemas for recent Kubernetes versions. For custom resources, users can point it to local or remote schemas; local schemas also make offline validation possible. Results can be produced as JSON, JUnit, TAP, or plain text. Documentation describes using its Docker images in GitHub Actions and GitLab CI, and the images are published to GitHub Container Registry. It is free, with a listed plan of free. Installation instructions cover Linux, macOS through Homebrew, and Windows. Its checks do not cover additional server-side validation, and its Go module interface is still work in progress and unstable.
